  1. My guess is that that design would be far too stiff. It might make a good canoe paddle.
  2. Here's an alternative theory. Design is based on a Bruneschelli dome. The big flat area provides no structural strength and is not meant to be under much tension or compression. It's like covering the skylight in the Florentine dome with a thin membrane. This allows the violin to have a big, thin area in center and acts kinda like a drum. Revolutionary design for the period. Before this they typical Florentine arch is characterized more like the back of a violin. Much thicker in the center than at the edges. This is pretty contemporary with the golden violin age and ever
  3. Not sure what you're saying no to. My version of history or if you can judge how well a belly has been carved by how much it bends when strung and tuned?
  4. You 2 can both be right. Here's how it went down according to me. In the beginning some luthiers made their belly plates too thick and their violins sounded bad. Others made their bellies too thin and they sounded good until they cracked. But a few got it just right and they were thin enough to sound good, but thick enough they wouldn't crack... They just sagged a little. That's how you know you got it just right. A little sag in the middle. That's how they KNEW they had a good violin. A little sag in the middle. Perfect belly thickness. So now, when someone wants to make a
  5. Nature of the beast with classical music. Everyone dresses in same black pants/dress, and everyone must play instruments that look like the standard. Very different than '80s hair rock where everyone gets to pick their own pattern of spandex pants. If I remember history right, we can blame some Italian duke for setting the violin standard. I blame France for the metric system.
  6. I'd say it's a coinflip between a future of electro-synth and lasers or a bunch of Ewoks banging on rotten logs singing "Yib nub". Electric jaw harps should never be a thing. I'm 75%-80% certain of this. I am hoping for an inflatable cello some day.
  7. Why doesn't anyone take the time to model a cigar box violin?
  8. I'm running with several subjects here so forgive me. 1. I have a math model of the violin shape and have taken it to extremes on what I still consider to be a violin shape. How skinny can it get and still be a violin? How fat can it get and still be a violin? How wide can the c bouts get and still be a violin? 2. I think speakers and violins probably have a lot in common when it comes to the physics. I bet if you took a violin body and cut a big hole in front and mounted a speaker driver, it would sound pretty good, lol. If so, the reverse is probably true as well. Also the hi
  9. What happens is acoustically complex. Made these drawings to attempt to illustrate. 1st 2 waves are a combination of a high frequency and low. 2nd pair of waves is "muffled". I've done something to reduce the amplitude of the high frequency while leaving the low frequency alone. Lots of ways to do this. Wood is a good muffler as is fiberglass packing. 3rd pair of waves is what I call mellow crispiness. Rather than just reduce the high frequency, I've modulated the amplitude using the low frequency. It's very pleasant compared to muffling. Perfect quiet between the low frequenc
  10. If you mean on the "baritone", if (on this model) you max out the shoulders adjustment and minimize the corners adjustment then the c bouts are shaped wrong. Max shoulders with max corners works, as does min shoulders and min corners. If both adjustments are medium then the shape becomes very similar to the Strad. This version is the least corners I can get while at max shoulders.
  11. Here's a family of cellos made off my template. 1. Tenor. Nearly identical to Strad cello. Little more open in the upper/center bout transition. 2. Counter Tenor: Narrower shoulders/hips than tenor. Should have clearer treble and softer bass. Better ergonomics for playing high on fingerboard. 3. Baritone: Broad shoulders and hips. Full corners. Mellow treble with crisper bass. 4. Gamba: Long c bouts to aid in pizzicato and make it more comfortable to play on knee like a guitar.
  12. That drawing is from 1511 if I remember right. I have working definitions of these classes which I'm sure some will disagree with: Fiddle: any stringed instrument that can be bowed or plucked. Viol: Tech advancement. Instrument is made like a modern violin with two plates between ribs. Viols are fiddles but unlike medieval fiddles which were carved out of a single block of wood, and unlike bowed lutes which are formed out of multiple ribs on a mold. Viola: Viol optimized for bowing. Finger board is lifted off soundboard and radiused. Radiused bridge. Tailpiece lifted off
  13. During the period, the same exact instruments were plucked or bowed. Called "geigen" which is German for fiddle/violin. Very archaic and has a guitar like bridge. They had separate bowing bridges that could be stuck under the strings to change key and raise strings for bowing, or could be played just like a lute. This is just one hair from modern violin design.
  14. Based on hi fi speakers, yes; shape has a massive effect on sound quality. Most importantly, all speaker drivers are rated for a certain volume of box and size of sound hole. Get that wrong and the speaker will sound terrible and the driver can even self destruct, overheat or be too powerful against too small a volume and deform. This is certainly true of fiddles as well. Most important to making them work is getting the interior volume right and the f holes right. Also the profile of the f holes is very important. A nice smooth, trumpeted profile can make a smaller f hole act like a bigg
  15. Maybe what you are looking for is "catenoid" if your CAD system can create that shape. A section out of one is actually the ideal shape for a fingerboard. Here's what one looks like. This one is way to fat. Imagine stretching this shape out very tall so the top is the radius at the nut, and bottom is radius at bridge... It would be almost a cone. Almost. A cone with a little bit of a waste. Then chop a section out of it, and wala.
